 What, then, is it to treat of philosophy, unless to lay down the rules of the true religion by which we seek rationally and adore humbly God, who is the first and sovereign cause of all things? Hence it follows that the true philosophy is the true religion, and reciprocally that the true religion is the true philosophy. De Divina Praedestinatione, ch. 1; translation from Kenelm Henry Digby Mores Catholici, vol. 8 (London: Booker & Dolman, 1837) p. 198.
